overheating problem HELP!!!!!!!!!&

[Black 5spd]

today i had to take my supra to work it is about 10minutes drive in trafic, the car got very hot, i could not touch the valve cover because it was so hot (is that normal on supras?)
and the overflow tank was filled and spraing out on the street. and i looked for the temp sensot by the p/s bracket but i did not see it (i have a 7M-GE).
wheni drve her for even a few blocks i have coolant leaking down the block, looks like it is coming from the water pump gascket.
if you could send me a pic of where is the sensor.
i am getting a new radiator on thursday, so i gues no driving till thursday.
